Ecodesign of a process for dimethyl carbonate: Influence of the degree of modelling of the methanolysis of urea

The environmental performance of emerging bio-based technologies must be assessed at an early stage their development, when the process can still modified for sustainable optimization, i.e. including environmental, social and economic aspects. Life Cycle Analysis (LCA) methodology is already recognized as effective solution analysis. However, data obtained laboratory scale are incomplete in initial eco-design a new synthesis route, which complicates inventory life cycle. Coupling modelling/simulation tool with LCA has proven to providing data. simulation based on selection models allowing energy optimization technology developed production scale. choice reaction separation steps will certainly have significant impact results assessment. This article dedicated study degree complexity modelling pathway assessment methanolysis urea produce dimethyl carbonate (DMC).
